For our latest lookbook, we've collected ten interiors with built-in furniture that adds storage space and tailor-made seating solutions to homes.

From benches that function as window seats to custom-made shelving and sofas, built-in-furniture can be both decorative and practical, while also creating more space in interiors with small footprints or adding interest to larger spaces.

Among the 10 examples below is an apartment in a former hotel that features a completely custom-made interior and a Portuguese home filled with wooden joinery.

This is the latest in our series of lookbooks providing curated visual inspiration from Dezeen's image archive. For more inspiration see previous lookbooks showcasing plant-filled interiors, bedrooms with smart storage solutions and homes with vaulted ceilings.

GjG House, Belgium, by Blaf Architecten

This Ghent house has an irregular shape that curves around existing trees. As a result of the unusual shape, much of its furniture was built especially for the house, including a wooden storage wall in the kitchen that holds cabinets and shelving.

The interior of the undulating house is free from supporting walls, and with storage hidden away, the tall home feels very spacious.

Nicolai Paris, France, by NOA

A hotel in Paris' Marais area was turned into an apartment by Network of Architecture, which added custom-made oak furniture to the Nikolai Paris home.
